Sudoku Daily Challenge

Play Sudoku and compete with other players from all around the world.

Do you like to play Sudoku? How good are you comparing with others? Now you can find it out. Each day, "Sudoku Daily Challenge" generates 3 Sudoku puzzles dynamically with 3 different difficulty levels: easy, medium and hard. You have the choice of which one to play. Also, people all around the world, like you, will play the same puzzle at the same time. The time each player used to finish the puzzle will be recorded, and the statistics (average, fastest, etc.) will be updated at real time. When you finish it, you can see your rank among all the players who have played the same Sudoku.

This game is FREE. No account or sign up is required. For each Sudoku, you can play as many times as you like, but the App records your time every 8 hours. That is, if you play the same Sudoku within 8 hours, only the first play is recorded and counted. The App identifies you by assigning you the random Id. If you delete the game or clear the data of this App, your Id will be erased, and you will be assigned a new one. But, there is no way to recover the "Old" records. The App does NOT access any resources of you phone: contacts, camera, location etc. Security and privacy is my first priority when I develop this App.

Please send me feedbacks about this App. Have fun!
